USING SCREW-MOUNT TAKUMAR LENSES
Conventional screw-mount Takumar lenses (both
Super-Takumar and SMC Takumar) can be easily
mounted onto your camera by attaching them
first to a Mount Adaptor K. However, when
Adaptor K is used, the following is true:
Due to the difference in coupling systems, the
automatic diaphragm will not function.
Full-aperture metering lenses will function as
stop-down metering lenses.
a How to Use Mount Adaptor K
1 Screw the conventional Takumar lens into the
Mount Adaptor K.
2 Attach the Adaptor/lens unit to the camera
body by aligning the red dots © and © , and
turning the lens clockwise until it locks with a
click. (This takes slightly less than a quarter of a
revolution.) ^
3 To remove the lens, leaving the Mount Adaptor
K attached to the camera body, simply unscrew
the lens counterclockwise. Other screw-mount
